  Krebs Cycle

  
• Anaerobic


  .

  
• 4 stages 


  • Glycolosis- phosphorylation of glucose in cytoplasm
  • Link reaction- Decarboxylation + Dehydrogenation of pyruvate in matrix of mitochondria
  • Krebs Cycle- In matrix of mitochondria
• Lipids 


  • Hydrolysed into glycerol + 3 fatty acids
  • Glycerol converted into triose phosphate for gylcolosis
  • Fatty acids broken down into 2 carbon compounds for acetyl coenzyme A in krebs cycle
• Proteins


  • Hydrolysed into amino acids
  • Amino group removed
  • 3 carbon compounds converted into pyruvate
  • Longer R groups with 4 and 5 carbons converted to intermediates in krebs cycle
• Oxidative phosphorylation (4)
